I

Prior art constructions of partition walls had the disadvantage of notallowing for variations in the dimensions of the main walls and hencerequiring adjustment on the site, which resulted in waste of both timeand materials, and required skilled labor. Also, the adjustment requiredprevented re-use, so that such partition walls could not be termeddemountable.

The special section used for the top and bottom abutments and for theframes consists of a U-section, the edges of which are bent inwards andthe base of which bears on the floor or ceiling, in the case of thebottom and top abutments respectively. A T extends from the center ofeach of the arms of the U and the web of the T is perpendicular to thearm of the U, while the crossbar of the T is of a length equal to halfthe height of the arms of the U, and the two edges of the said crossbarare bent inwards.

The special three-channel section for the partition wall comprises achannel having a horizontal entry for the introduction of the connectingmember whereby two sections are twinned, said connecting member bringsecured by resilient fasteners of a known type; a larger channel havinga vertical entry to receive the facing panel, said channel being dividedby a vertical partition to form a narrow channel to receive theretaining section for the facing panel concealing the jacks and ensuringcontinuity as far as the abutment. The three-channel section is used ina twinned arrangement, and an insulating filling can be introduced asindicated hereinbefore by a connecting member which determines thethickness of the partition.

The details of the invention will be apparent from the description withreference to the accompanying drawings.

FIG. 1 is a perspective of the assembly formed by a bottom abutment, apartition wall, and a top abutment, before the fitting of the facingpanels which conceal the jacks and provide architectural continuity.

FIG. 2 is a similar perspective view to FIG. 1 but with the spacesbetween the partition wall and the two abutments being filled in.

FIG. 3 shows the incorporation of glazing at the center of the partitionwall, the glazing being secured by glazing beads of a known type.

FIG. 4 is a horizontal section of the corner connection of two partitionwalls at right angles to one another.

FIG. 5 is a horizontal section of the frame with a hinge clipped on andsealing members of known type.

Referring to FIGS. 1 and 2, the top and bottom abutment members consistof the U-section l and the T-sections 2, while the section for thepartitioning wall consists of a channel 3 having a horizontal entry forthe introduction of the connecting member 14 visible in FIG.

3, by means of which the two sections are twinned; the channel 4 toreceive the facing panel 7 and resilient fastening means; the channel 5to receive retaining sections 6 for the facing panel 8, which concealsthe jacks 9; l0, and the insulating filling between the two facingpanels 7.

Referring to FIG. 3, the twinned partitioning wall has glazing 11 in themiddle, said glazing being fixed by four rubber glazing beads 12 fixedin the channel 4 of the section; the glazing 11 rests on a wooden member13 which itself bears on the member 14 by means of which the twosections are twinned.

Referring to FIG. 4, the retaining sections 6 are fitted in the channels5 of the sections to receive the inner facing panels 15 and the outerfacing panels 16; the latter are retained at the outer corner by anX-section 17 which allows the facings l6to be fitted and fixed from theoutside of the structure; reference 18 denotes a corner insulatingblock.

Referring to FIG. 5, the two frame members are formed by the samesection as is used for the abutments, the hinge 19 being clipped on toone of the T- sections, the symmetrical channel of the other framemember acting as a bolt for the striking plate 20 of the door 21;reference 22 denotes plastic gaskets of known type. The symmetry of thesection enables a double door to be fitted if required.
